Root Cyclone Technology
This is a patented Dyson technology that uses 100,000 G's of centrifugal force in cyclones to filter dust and remove dirt from the airflow efficiently. The Root CycloneÔ delivers higher suction power by making the air stream spin, subjecting it to centrifugal force, which throws the dirt and debris out of the air. Because the airflow is unobstructed and because there are no filters or bags to clog, the suction power remains constant.
